Y o all ywhom /-t may cof/cem Be it known that I, JOHN J. Bowne, Jr., a citizen of the United States, residing at Pensacola, in the .county of Escambia and.

the State of Florida, have invented a new and useful Improvement in HotVater and Ice Bag Closures or Stoppers, of which the following isa specification.

This invention relates to Stoppers, and more particularly to the class Of quick detachable Stoppers for containers such as hot water and ice bags or the like.-

The primary object of the invention is the provision of a stopper of this character wherein the employment of screw threads upon the stopper is eliminated and the saine is securely locked in the vmouth cf a container to positively close the same against leakage and to permit the quick detaching of the stopper when 4the occasion requires.

Another obj ect of the invention is the provision of a stopper of this character wherein the usel of a disk washer is dispensed with 'as the same becomes worn by constant use and by reason of excessive screwing of the ordinary stopper used in hot water and ice bags for the closing thereof to avoid leakage,the stopper being of novel construction for the quick detachment and attachment thereof with dispatch.

'A further object .of the invention is the provisionk of a stopper of this character wherein the gasket or resilient ring is of ya construction to permit the expansion vthereof under the action of the `contents of the bag or container and thus obviatev any fpossibility of the leakage of the contents from the same when the bag or container is in use.

A still further object of `the invention fis the provision of a stopper of this character wherein the. construction thereof permits the use of a flexible ltube for converting the container or bag into a syringe, kthe tube being positively fastened in the-stopper so as `to obviate the pulling away of the .tube there.- from irrespective -`of -thestrain .exerted upon the tube. i

,A still further object Vof :the invention is the provision of a stopper .of `this character' wherein theY same is formed -withan outlet bore or :passage and 4.carries aremovable cap,

\ the' bore also being"'designed to receive a ssl' fieible tubewhich canbe readily and easily detmhably therein.

plication of which will be indicated in the y appended claims. y

In the accompanying drawings:

I Figure 1 -is a fragmentary vertical longitudinal sectional view vthrough a hot water bag rshowing the stopper constructed in accordance with the invention applied; Fig. 2 is a similar 'view showing the stopper in vertical Sectional elevation; Fig. 3 is a view similar to Fig. 2 with the cap of the stopper removed anda portion of a flexible tube fastened inthe stopper; Fig. t is a fragmentary sectional view `through an icebag'showing a slight modification of stopper for use therewith, the stopper being partly in section. 1 I f Similar reference characters indicate corresponding parts throughout the several views of the drawing.

Referring to the drawing in detail, espe-v cially Figs. 1 to 3 thereof, A designates a portion ,of a hot water' bag having theusual v 'diameter reduced and `the `annular shoulder '12 thus Aprovided is 4flared lfor a presently described.

Removably'tted Within this lining is a stopper whose body 13Vis formed with ,aj reduced external-ly threaded outer end-'1145 for the detachable mounting thereon of "a cap in which is -externallyf'sknurled Fat-.1.15.

purposev The ring l0 he- 1 55 nally beveled annular shoulder 25 which coto permit the quick and easy application and removal of said cap, while on the top of the latter is formed a knob 17 with which loosely engages a ring 18 at one end of a flexible hanger 19, the same being also connected with a tab 2Ov on the funnel mouth C and in this 'manner the cap is prevented frombecoming lost when removed from the stopper body V13, as will be clearly apparent. p

The stopper body 13 has a portion which is adapted for insertion within the ring 10 and the portion which is thus adapted for insertion is provided with an external groove 22 having an end flange 23 and concentrically with respect to the groove' 2 and seated within this groove is a packing ring or gasket 25. This gasket is preferably of substantially inverted U-shape having an inner wall kwhich engages with the wall of the groove 22 and -having an outer wall which is spaced from the inner wall, the outer'wall being adapted to contact with and make a close lit with the inner wall of the ring 10 when the stopper body 13 is inserted" therein. The free edges of these walls are preferably tapered.

lThe arrangement of the outer wall of the gasket with respect to the stopper body 13 and particularly with respect to the flange 23 is such that the-open space between the wall of the gasket is in open communication withthe interior of the container with which the stopper is associated, so that the liquid within the container may have free access to the space between the wallsl of the gasket.

As before stated, the vouter wall of thev gasket has a close 'fit with respect to the ring l0 sothat when under any circumstancesv the liquid within'the containercontacts with the gasket, it enters the space between rthe'w'alls of the gasket exerting a pressure outwardly upon these walls thereby pushing the lwalls of the gasket into more intimate contact with the "portions of the ring 10 with which they engage and effectively preventing the passage `of any liquid around the'outside of the gasket and `the greater'the pressure exerted upon the gasket'by the liquid', the .more firmly and effectively does the gasket engage the wall of the groove 22 and the wall 4of the ring'lO.

The stopperv body '13 may be formed above-its grooveand gasket `with an exteroperates with the shoulder 12 internally tof thering 10, when the stopper member is' locked in positionl therein'for closing the hot water bag. v l 7 *1 Thefstopper vis inserted within the yring 10 by a' substantially .lineal pushing-in movement, requiring but a slight amount of forcel 'to overcome'the rictional engage- .ment betweenthe guter. wall of. the gasketand the inner wall of the ring 10. The stopper is held in its most inward position by any suitable means such as that shown in the drawing and about to be described.

Projecting from the stopper body 13 at diametrically opposite points thereof yare pins 26 which are adapted to engage in L- shaped slots 27 formed in diametrically opposite points of the ring 10 and opening through the upper edge thereof, the inner ends of the slots 27 being formed with olfset notches 28 forming seats for the pins 26 when thel same have been inserted through the open ends of the slots 27 and the stopper body 13 turned within the ring 10 for the engagement of the pins 26 in the seats 28, thereby securely fastening the stopper body in place against accidental removal.

Formed axially through the Stopper body 13 is a bore or passage 29 having flared ends 30 and 31 respectively, the end 31 being of greater extent than the end 30, and into either of the same is adaptedA to be receive 'l a. hollow truncated conical yshaped spreader member 32 which is adapted to be inserted in the end of a flexible tube 33 when passed through the bore 29 for the fastening of the said tube inthe stopper body 13 in the flared rend 30, as is clearly shown in Fig. 3 of the drawing, the spreader 32 being formed with a looped handle 34 to permit the conventientapplica-tion and removal of said spreader to andl from the tube 33, it being understood of course that when the tubel 33 is inserted in the stopper body 13 it has been previously removed from the ring 10 in the neck of the bag. lVhen the tube 33 is detached from the stopper body 13 the spreader may be placed within the flared end 31 of the bore 29 as is clearly shown in Fig. 2 of the drawing, and thc cap 15 will prevent the loss of *theA said member held therein.

In Fig. 4 there is shown a slight modification of the inventioin'whei'ein 1) designates a portion of the body of an ice bag having the usual neck E in which is fitted the ring in the neck E similarly to the'ring 10 in the' y neck VB of thebag A., and detaehably fitted within the ring 35 is the stopper which coni'- prises Va hollow substantiallycup. shaped body 36 formed with a reduced inner-end 37 having anfeXternal `channel or groove 38 to receive the expansible. gasket 39 which is identical tothe gasket 24, and this body 36 i is fastened in the *ring 35 through the me# dium `vofV the pins 39 and slots 40 `carriedby and Yformed inthebodynand ringv respec-l tively. The body is formed atits 4vouter end with a knurled external bead 41 to permit the'convenient application and'removal o thel stopper, as willbe obvious.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the herein described closure will be readily app-arent and, therefore, a more extended explanation has been omitted.
